ENGINE 91 D. Alternator and AC Belt : Alternator and Ac Belt Removal : 1. Remove the power steering belt (stretch belt) by cutting the same. NOTE Do not reuse the power steering pump belt once removed. 2. Remove the tensioner cap (1) and loosen the tensioner bolt (2). 3. Reduce the belt tension by rotating the tensioner screw (3) in clockwise direction (Tightening direction of a RH threaded screw) and remove the belt. Inspection : Inspect the Alternator belt for wear, cracks and signs of failures. Replace if necessary. Fitment : 1. For fitment, first place the belt, and then tighten the tensioner screw (3) by rotating it in the anti-clockwise direction (Loosening direction of a RH threaded screw) . 2. Tighten the tensioner bolt (2) to a torque of 4 Kgm and fit the cap. 3. Adjust the belt tension. Alternator and AC Belt Adjustment : 1. Remove the tensioner cap (1) and loosen the tensioner bolt (2). 2. Adjust the belt tension to as follows: a. To reduce the tension rotate the tensioner screw (3) in clockwise direction (Tightening direction of a RH threaded screw) b. To increase the tension rotate the screw (3) in anti-clockwise direction (Loosening direction of a RH threaded screw) . Keep belt tension in given range .which is as follows. For new Belt Tension for new belt = 268 ± 10 Hz NOTE This value to be measured in the span between alternator and AC compressor pulley (marked as “A” in the above image) Then run the engine for 15 mins. Now the belt has to be re-tensioned to 244 ± 10 Hz. For reusing same belt In case of reusing the same belt, it should be tensioned to 244 ± 10 Hz.
